The two intestines and their parts
El intestino delgado has three parts: el duodeno, el yeyuno and el íleon. El intestino grueso starts at el ciego, with el apéndice attached, and goes on as el colon in four stretches (ascendente, transverso, descendente and sigmoide), then el recto and el ano.
Three pairs of salivary glands
The salivary glands are las glándulas salivales: la parótida in the cheek, la submandibular under the jaw and la sublingual under the tongue. The second is also called la glándula submaxilar.
El colon has no accent. With one, Colón is Columbus and el colón a currency.
Only seven of the 25 names are feminine: la boca, la faringe, la lengua, the three glándulas and la vesícula biliar.
Questions and answers
How do you say digestive system in Spanish?
El aparato digestivo or el sistema digestivo; WordReference lists the two as one entry. The tube itself, from the mouth to the anus, is el tubo digestivo, the digestive tract.
How do you say intestines in Spanish?
Los intestinos, or el intestino for one. The small intestine is el intestino delgado and the large intestine el intestino grueso. All three are masculine.
How do you say gallbladder in Spanish?
La vesícula biliar, a feminine noun. WordReference notes that biliar is often left out, so la vesícula alone usually means the gallbladder.
Is it colon sigmoide or colon sigmoideo?
Both. WordReference gives el colon sigmoide and el colon sigmoideo in one entry, and the Spanish dictionary of the U.S. National Cancer Institute uses colon sigmoide. The drawing shows el colon sigmoide, and both count when typed.
Where were the Spanish names checked?
Each name and its gender in WordReference and in SpanishDict or the Cambridge Spanish-English dictionary. The stretches of the colon and the salivary glands were also read in MedlinePlus en español and the Spanish dictionary of the U.S. National Cancer Institute.
